For the RSS feed, this is not exactly what I’m looking for.

@brikou it’s the only plugin that I know of that comes close to what you need. You’d either need to code one or hire a developer to do what you need.

Btw, please upload your BP-compatible or BP child theme in wp-content/themes/ and not in wp-content/plugins/buddypress/bp-themes/ Good that the latter way works for now, but that’s not the best practice.
